Sydney Metro-Central Walk
Construction work is currently in progress to expand the Metro system under Sydney Harbour and the Central Business District (CBD) to include 41miles (66km) of twin tracks and 31 stations by 2024.
Sydney Metro-Central Walk
The development of Central Station and the landmark Central Walk were awarded to international contractor Laing O’Rourke who proposed an innovative design with numerous benefits, including satisfying a key requirement that construction works needed to take place while keeping the existing station and train services operational.
Breedon Quarry Project
After reaching the limits of drilling and blasting without creating excessive vibration and dust for the surrounding environment, Breendon need to find another viable solution. Rock excavation specialists AJ Gammond provided an innovative solution.
Breedon Group Quarry Case Study
At Breedon Quarry valuable aggregates need to be extracted close to the nearby community of Breedon on the Hill. After reaching the limits of drilling and blasting that could be done without creating excessive vibration and dust implications for the surrounding environment, Breedon needed to find another viable solution.
City Rail Link Project
City Rail Link (CRL) is Auckland’s first underground rail line and the largest transport infrastructure project ever undertaken in New Zealand. CRL will transform the downtown Britomart Transport Centre into a two-way through-station, doubling the capacity, reducing travel times and supporting a growing population with a world-class transit system.
City Rail Link Project
he 3.45km twin tunnel underground rail link will run up to 42m below the city centre and includes the construction of two new inner-city underground stations (Karangahape and Aotea) and rebuilding the existing Mt. Eden Station.
Ventilation Design Systems in Tunnelling
Ventilation Design Systems in Tunnelling Three Key Ventilation Design Systems The Importance of Ventilation and Dust Control A critical aspect of any tunnel construction is ventilation design and dust control, so that workers exposure to fumes and dust are reduced to safe, acceptable levels. Silica or silicon dioxide is a naturally occurring and widely abundant mineral that forms a major component of most rocks and soils. Crystalline silica dust is the biggest risk to construction worke [...]
Ventilation Design Systems in Tunnelling
A critical aspect of any tunnel construction is ventilation design and dust control, so that workers exposure to fumes and dust are reduced to safe, acceptable levels. There are many types of ventilation design and dust control systems and as each tunnel is unique so is each ventilation design and dust control solution.
Melbourne Metro Tunnel Project
The Metro Tunnel provided some unique challenges for the ventilation design, including space and noise constraints plus the location on excavation works within the CBD. The design was created using Ventsim Design 5 to simulate ventilation, airflows, pressures, heat, gases, radon, fire and other key ventilation data to be considered, along with managing the financial constraints of the project.

Dust Control with T1055 Trencher
Green Civil rented a JMS-20-MDT from Grydale Rental to work alongside a Vermeer Trencher to manage the dust creating from completing trenching work in Sydney.
Greenbank Sewer Rising Main Project
The Greenbank Sewer Rising Main project was undertaken by Diona in November 2019, for the Logan Water Infrastructure Alliance and involved the installation of 5.6 kilometres of sewer rising main pipeline. They hired a JMS-20-MDT (Diesel, Track) dust collector from Grydale Rental to manage the silica dust created as a result of trenching through sandstone.
Fixed Unit Dust Collector Case Studies
Bulk Storage Handling (NSS)
Northern Stevedoring Services (NSS) - have two sheds located on the Port of Townsville where they store zinc and copper concentrate before distribution to their global customers
Coastal Powder Coating
Sandblasting generates large volumes of dust that can be toxic and small enough to be inhaled into lungs and thus can be hazardous to workers.
Crushing Plant Dust Extraction System
Our clients’ site expansion works, included a tender for a dust extraction system to manage dust created by two secondary and tertiary cone crushers and three screening plants. Grydale were awarded the contract to design, manufacture and install a Grydale JMS 48 F-Series Dust Extraction System. This unit provided 38,000m3/hr of air flow at -2.0kPA, which offered the capacity to extract dust from the two secondary and tertiary cone crushers and three screening plants.
